In general, I don’t like reading action fics much, simply because it’s very difficult to write well and is therefore written badly. Your action scenes were very well paced, and there was a lot of realism in that front, so congratulations. However, you should work on your choice of words and grammar in order to make your stories even better. My favourite parts were the interactions between characters; the dialogue was very realistic. I think that to engage the reader more, as the end was quite unsatisfactory, go into depth on YiFan’s feelings about ZiTao’s death, or even ZiTao’s feelings about dying now that he’s found YIfan, or regrets. I think that would have made it even better.
